I have to disagree with you,if you have read those enough threads about lcd vs plasma i am in 90% of those threads.
The lcd vs plasma threads has no closure,its still an ongoing debate in every forums.
While plasma still have the edge in some areas mainly viewing angle which won't matter for everyone unless they are unfortunate to view a tv at those extreme off angles,IPS based lcd tvs have wide viewing angles with only contrast shift and no color shift and tech used in HX92 series has neither,SPVA offers more then enough viewing angle for a couch of 3 people.
Color accuracy in lcd are more then a match for plasma what do you think the pros use a when adding CGI in movies/animation ,photoshop etc its a lcd monitor or trimastar pro monitor.
Infact a plasma produces color by dithering.
As far as Black level sure in pixel level the panasonic FHD plasma have the edge,but that edge can only be seen in a dark environment.
In day time or living room with significant ambient light the lcd still has the edge in contrast.
In the night time the VA based lcds can match or even surpass the samsung/lg plasmas,while the panasonic FHD plasma still have that edge,but then again you have local dimming lcd to challenge the panasonic VT plasmas.
Widely accepted by many pro review sites as the best tv is still a lcd the sharp elite apart from viewing angle its has the edge in pretty much every area.
which is why I said given the same price............the HX92, Sharp elite no doubt are some of the BEST tv's around but at what price? And yes I do agree LCD/LED are brighter and would have an advantage in bright ambient light but plasmas would still outperform most tv's in a dark room. And I'm not talking about comparing the BEST LEDs with the best plasma's. We all know for how long the Pioneer kuro was the king and why no LED/LCD tv could even come close..........and nothing can take that way from them. It is only until recently LED/LCD have got their act together and managed to come out with great tv's to match or ever surpass the kuro.
For someone on a tight budget I would still recommend plasma over LED/LCD, unless viewing in an extremely bright room with lot of ambient light.

since you talk about LED/LCD having better contrast ratio, black level, etc.......let me highlight the below from the same link:
Black level
Winner: Plasma TVs
Loser: LCD TVs
Runner-up: LED TVs
Contrast ratio
Winner: Plasma TVs
Loser: LCD TVs
Runner-up: LED TVs
Viewing angle
Winner: Plasma TVs
Losers: LCD and LED TVs
Runners-up: IPS-based LCD and LED TVs
you cant deny that it is plasma that was considered as reference level and NOT LED/LCD.
